We estimated mean undiscovered volumes of 3.65 billion barrels of oil, 1.85 trillion cubic feet of associated dissolved natural gas, and 148 million barrels of natural gas liquids in this area using a geology-based assessment methodology.

Small wetlands in this large area have hosted migratory birds for a long time, but with changes in agricultural practice and regional climate those habitats may not remain hospitable to the wild populations.

Includes hydrographic information from 2000 to last seven days, water-quality data, elevation, area, and capacity data and publications on Devils Lake, North Dakota in the Red River of the North basin.

Sixty-five sampling sites, selected by a statistical design to represent lengths of perennial streams in North Dakota, were chosen to be sampled for water chemistry and mercury in fish tissue to establish unbiased baseline data.

Sixty-five sampling sites, selected by a statistical design to represent lengths of perennial streams in North Dakota, were chosen to be sampled for fish and aquatic insects (macroinvertebrates) to establish unbiased baseline data.

Wetlands and oil wells shouldn't mix, but in some areas they do. This explains what problems may arise and how we study the effects of highly salty water produced by oil wells when it leaks into nearby wetlands and streams.

Consistent, historic, and up-to-date ground-water data, such as water levels collected at wells and springs, are available from the USGS National Water Information System as graphs, tables, or files to download.

Links by map location or station number to real-time stage and streamflow, real-time water quality, ground-water data, long-term hydrographs, and annual water-data reports to view and download for past and current water conditions in North Dakota.

Homepage linking the historic journey of Lewis and Clark and the research of the USGS in the same region with links to mapping history, remarkable points on the Missouri River, educational activities, photo gallery, and publications.

Description of the North Dakota stream-gaging program using a Missouri River streamflow-gaging station in Bismarck, North Dakota as an example explaining how and why the USGS collects stream data with photos and directions for visiting the station.

Trapping education manual for the beginning or inexperienced trapper intended to provide information on North Dakota's predators and furbearing animals and the basics on how to trap them using good trapping skills and sound fur management.

Consistent, real-time water data from streams, lakes, reservoirs, ground-water, and meteorological sites, are available from the USGS National Water Information System as graphs, tables, or files to download.

One of the greatest challenges for conserving grassland, prairie scrub, and shrub-steppe ecosystems is maintaining prairie dog populations across the landscape. Of the four species of prairie dogs found in the United States, the Utah prairie dog (Cynomys

A broad survey of regional patterns in stream flow nationwide. Maps and graphs summarizing streamflow conditions for water-year 2007 (October 1, 2006 to September 30, 2007) in the context of the 78-year period 1930-2007.

About 355,000 million gallons per day of water was withdrawn for use in the United States during 2010, a decline of 13 percent from 2005 and a substantial change from the level of about 400,000 reported from 1985 to 2005.

Consistent, historic, and up-to-date surface-water data, such as gage height (stage) and streamflow (discharge), collected at major rivers, lakes, and reservoirs, downloadable from the USGS National Water Information System as graphs, tables, or files.

Here we study effects of climate and groundwater on surface-water levels, the hydrological effects on wetland water chemistry, and the combined effects of climate, hydrology, and water chemistry on plant and animal communities of prairie pothole wetlands.

Summary of part of the USGS interdivisional Mississippi Basin Carbon project that will study the changes in climate and the environment through carbon cycle changes recorded in lake sediments in the Upper Mississippi River Basin.

This updated subset of USGS streamgages for which the streamflow primarily reflects prevailing meteorological conditions for specified years, screened to exclude sites where human activity affects the natural flow of the watercourse.

We use moderate resolution satellite data to assess live fuel condition for estimating fire danger. Using 23 years of vegetation condition measurements, we are able to determine the relative greenness of wildland vegetation susceptible to burning.
